Astorg portfolio company Lebronze alloys (LBA), a copper and nickel alloy producer, has acquired m Lego, a French manufacturer known for its copper alloy semi-finished products, from AUREA Group.
Headquartered in France, LBA’s range of products, each with combined properties such as thermal conductivity, ability to withstand friction, and electrical performance, makes them critical components in a large variety of systems and end-markets – including aerospace, medical devices, energy, electronics, and luxury – serving over 1000 customers worldwide.
Astorg took up a shareholder position in the business in 2024 to accelerate its growth plans, notably through targeted acquisitions. With the private equity firm’s support, LBA is expanding globally and reinforcing its leadership position with a focus on quality, innovation, and operational excellence.
Founded in 1894 as Etablissements Maurice LEGO, m Lego specialises in the production and sale of high-quality copper alloys in the form of semi-finished products, including round bars, flats, profiles, and other custom sections. Since January 2011, m Lego has been part of AUREA, a European group focused on the circular economy.
The transaction involves 100% of m Lego’s shares, previously held by AUREA, and represents €34m in revenue as of 31 December 2024, with 85 employees joining the LBA Group.
Following the closing of the acquisition, both teams are actively preparing for a seamless integration.
